Summary:This paper proposes a new optimal cooperative jamming (CJ) strategy in the analog network coding (ANC) system against both external and internal eavesdroppers. Firstly, we derive the ANC system security capacity with CJ against eavesdroppers. On this basis, we analyze the jamming power allocation between two time slots subject to a total jamming power constraint. The simulation results show that using CJ in the ANC system can make eavesdroppers decode no confidential information, and the optimal jamming power allocation factor is one, which means that the optimal CJ strategy in the ANC system is to use all constrained jamming power on sending jamming signals only in the first time slot.
